Water pump...if everyone can keep their cool!

Below is a pic of my water pump. As you can see, no soft braided hoses on mine, unfortunately! So would those existing fittings to the Pex pipe likely be barbed? If so, then taking out a section of Pex and putting in a loop of soft braided hose would be pretty straightforward.

If you want to replicate what the factory has done you'd need the special tool designed to properly clamp those Oetiker clmaps. You can avoid all this by instead using compression fittings such as those offered by Sea Tech or Sharkbite. Just cut the PEX where you want to and install the fitting - done. However, if once disconnected there's enough play in that PEX shown in your pic to allow moving the PEX out of the way I'd just leave it all as is and use a set of adapters to connect to a length of soft wall braided hose. You can buy pump silencer kits from Shurflo and Valterra that consist on this braided hose already terminated with 1/2" fittings but they're only 3' long each. My own experimentation indicates you want at least 15' on the pump output to adequately quell all the vibration and thus noise, that's why I used a 25' length of fresh water hose instead.
